Apparently it's the weird things you are doing that makes the window 
manager mad.

Your startup class is a form that you hide when it is shown, by calling 
the Hide() method in Form_Show(). If you remove that, the window does 
not appear in the taskbar.

The possible reason for this behaviour is that since Qt5, the window 
properties must be defined after the window has been shown, otherwise it 
does not work. As you hide the window during its show event, maybe it 
creates a bad interference.

I will check again if I can define the window X11 properties before 
calling the Qt show method.

Otherwise, why doing that? Why using an hidden window as startup form? 
If you don't want it to be visible, don't define it as startup form so 
that it is not automatically shown.
